The International Longshore and Warehouse Union, Hawaii's largest private sector union, announced Tuesday it will support Democratic Honolulu Mayor Mufi Hanneman for governor, though Hanneman hasn't made his campaign official yet. The electrical workers union backed former Rep. Neil Abercrombie for the Democratic nomination.

In accepting the electrical workers endorsement, Abercrombie accused Hanneman of putting an important rail project at risk by looking to seek higher office. "It is in the public's best interest for the mayor to stay in his current office for this critical project to have a proper start," Abercrombie said — little more than a week after resigning from the House to run for governor, in the middle of the final push for health care.
